Living abroad does not automatically eliminate all U.S. tax obligations. While many expatriates focus on the foreign earned income exclusion (FEIE) to avoid federal, state, and city income taxes, the payroll (self‑employment) tax that funds Social Security and Medicare often remains payable unless specific steps are taken.
Payroll tax versus income tax
- Payroll (self‑employment) tax: 6.2 % for Social Security, 1.45 % for Medicare, plus an additional 0.9 % Medicare surtax on high incomes. Because self‑employed individuals pay both the employee and employer portions, the effective rate is roughly 15 %–16 % of net earnings.
- Income tax: The FEIE allows U.S. citizens to exclude up to $112,000 (2024 amount) of foreign‑earned wages from federal income tax. Most states do not tax foreign income, and only a few jurisdictions impose a state or city income tax on expatriates.
Why the FEIE alone is insufficient
Qualifying for the FEIE removes federal income tax on the excluded amount, but it does not exempt self‑employment tax. A freelance web developer who spends a year in Thailand, for example, would still owe roughly $15,000–$16,000 in payroll tax on $100,000 of earnings because the income is still considered self‑employment income for U.S. tax purposes.
Using a foreign corporation to shield payroll tax
- Establish a bona‑fide foreign corporation (e.g., a limited company in a jurisdiction that permits non‑resident ownership).
- Become an employee of that foreign corporation and receive a salary from it.
- Because the foreign corporation is not a U.S. employer, it does not remit U.S. payroll taxes on the employee’s wages. The employee’s compensation is therefore exempt from U.S. self‑employment tax, provided the arrangement satisfies the “foreign corporation” rules in the Internal Revenue Code (e.g., Section 861 and related Treasury regulations).
Caveat: The foreign corporation must be a genuine entity with its own substance, governance, and operations. Token companies created solely to avoid U.S. tax can be recharacterized by the IRS, leading to penalties.
Additional tax advantage: hiring non‑U.S. workers
When a U.S. business hires employees located outside the United States, the employer generally does not owe U.S. payroll taxes on those wages. By routing all hiring through the foreign corporation, an expatriate can:
- Pay foreign workers at market rates without the additional 10 %–12 % payroll tax burden that would apply to U.S. employees.
- Reduce overall payroll costs while maintaining a global talent pool.
Practical steps for U.S. digital nomads
| Step | Action |
|---|---|
| 1 | Verify eligibility for the FEIE (must meet the bona‑fide residence test or physical presence test). |
| 2 | Form a foreign corporation in a jurisdiction that allows non‑resident shareholders and offers reasonable administrative costs. |
| 3 | Draft an employment agreement that specifies salary, benefits, and reporting obligations. |
| 4 | Ensure the foreign corporation maintains proper books, a local bank account, and a genuine business purpose. |
| 5 | File Form 2555 (Foreign Earned Income Exclusion) and Form 1040 with the appropriate schedules to claim the exclusion and report any remaining U.S. taxable income. |
| 6 | If the foreign corporation pays you a salary, report that salary on Form W‑2 (issued by the foreign entity) and on your U.S. tax return, but no self‑employment tax is due. |
| 7 | Keep detailed records of all foreign‑entity activities to defend the structure in case of an IRS audit. |
Risks and considerations
- Substance requirements: The IRS may disregard a foreign corporation lacking real economic activity, treating its income as directly earned by the U.S. owner.
- Reporting obligations: Owners of foreign entities must file Form 5471 (Information Return of U.S. Persons With Respect to Certain Foreign Corporations) and possibly Form 8865 for foreign partnerships. Failure to file can result in significant penalties.
- Tax treaty nuances: Some jurisdictions have tax treaties with the U.S. that affect how income is taxed and reported. Review the specific treaty provisions before establishing a foreign entity.
- State tax exposure: A few states (e.g., California, New York) may still assert tax jurisdiction based on domicile or residency, even if the FEIE is claimed.
Bottom line
For U.S. citizens working abroad, the foreign earned income exclusion removes most income‑tax liability, but payroll tax remains a sizable cost unless a foreign corporation is used to receive compensation as an employee. Properly structured, a foreign entity can also enable hiring non‑U.S. workers without incurring U.S. payroll taxes, delivering additional savings. However, compliance with IRS substance rules and filing requirements is essential to sustain the tax benefits.
